Pronunciation

  • UK: /ɔː.dɪˈtɔː.ɹi.əm/[1]
  • US: /ˌɔ.dɪˌto.ɹi.əm/[1]

Etymology

It is borrowed from Latin audītōrium (“lecture room, audience”),[2][3][4][5] the neuter of the adjective audītōrius (“of or for hearing”) used as a noun,[2][3][4][6] literally "a place where something is heard".[3][6] Klein also glosses it "hall of justice",[6] and Collins "a judicial examination".[7] Barnhart derives the adjective from audītor (“hearer, listener”),[4] and Etymonline, Klein and Merriam-Webster from audītus, the past participle of audiō (“to hear”),[3][6][8] which Etymonline traces to Proto-Indo-European *au- (“to perceive”).[3][9] In Medieval Latin the word especially meant the reception room of a monastery.[3][2] It gradually replaced the earlier English auditory, from auditorie (“audience; hall of assembly”),[4][10] and in Old English the Latin word had been glossed Old English spræchus (“speech-house”).[3]

Earliest recorded meaning

A place for hearing, in a general sense: early 17th century, now rare.[5][11] Merriam-Webster dates the sense "the part of a public building assigned to the audience" to 1640,[8] while the OED first records it in Ephraim Chambers's Cyclopædia (1728),[2][4] and Etymonline in 1727.[3]

Semantic evolution

In English the word took over from auditory, which in Middle English, from about 1384 in the Wycliffite Bible, meant an audience or a hall of assembly.[4][10][3] The OED notes that in early churches it was applied to the nave,[2] and that in the United States it came to mean the whole building, not only the part where the audience sits;[2][5] Collins labels that sense American and Canadian.[7] Historians have used it since 1863 for the reception room of a monastery, after Medieval Latin.[2]
